Description
M/A-COM’s SW-289 is a GaAs MMIC DPDT switch in a low cost SOIC 14-lead surface mount plastic package. The SW-289 is ideally suited for use where very low power consumption is re q u i re d .Typical applications include transmit/receive switching, switch matrices, digital step attenuators, and filter banks in systems such as:radio and cellular equipment, PCM, GPS, fiber optic modules, and other battery powered radio equipment.
The SW-289 is fabricated with a monolithic GaAs MMIC using a m a t u re 1-micron process. The process features full chip passivation for increased perf o rmance and re l i a b i l i t y .
